Can dependant values based on a group of values instead of single values?

 Can i setup dependant values based on a group of accounts instead of a single account?

Example:

1. If users select either account 1200, 1201, 1202, 1203, the sub-acct (dependant segment) will show a list of sub-acct for selection.

2. If users select either account 2001,2002,2003 or 2004,  the sub-acct (dependant segment) will show another list of sub-acct for selection. 

We cannot maintain dependant values individually for all the accounts because it will be a very heavy maintenance. We want the dependant values to be based on a group of independant values. Can this be done?
